    Abstract: The invention relates to unsaturated oligophenol cyanates of the general formula (I) [A-]n[B-A-]xB[-A]m, in which A is a group of formula (II) and B is a group of formula (III), where R , R and R are each hydrogen or a bond with a group B, there being either one or two bonds with B; and both R and R as well as R and R separately or jointly represent a direct bond or hydrogen and a bond with a group A, there being either one or two bonds with A. The indices m and n are 0 or 1 but not both 1 at the same time and x is a whole number between 0 and 10, where at least one of the numbers m, n and x is not 0. The above unsaturated oligophenol cyanates can be prepared by reacting the corresponding oligophenols with chlorine cyanide. They have a low viscosity and owing to their double bonds are able to undergo free-radical polymerization. They are especially suitable for use as matrix materials for fibre-reinforced composites and for radiation-curable varnishes and coatings.
